The new release of ArangoDB 3.2 is just around the corner and will include some major improvements like distributed graph processing with Pregel or a powerful export tool.

As this is an important change and many questions reached us from the community we wanted to share some answers on the most common questions. Please find them below

ArangoDB wins Red Herring Top 100 Award
Jury selected ArangoDB out of 1.200 promising companies in Europe and confirms growing importance of native multi-model databases.
ArangoDB, the native multi-model database, announced today it was selected as a winner for
Red Herring Top 100 award for the European business region.
Red Herring Top 100 Europe enlists outstanding entrepreneurs and promising companies. Winners are selected from approximately 1,200 privately financed companies each year in the European Region. Since 1996, Red Herring has kept tabs on these up-and-comers. Red Herring’s editors were among the first to recognize that companies such as Alibaba, Facebook, Google, Kakao, Skype, SuperCell, Spotify, Twitter, and YouTube would change the way we live and work.
“It was exciting to see so many great ideas and teams from across Europe gathering in Amsterdam for Red Herring Award 2017,” said ArangoDB CEO Claudius Weinberger. “Developers, architects and CIOs around the globe have many options when it comes to databases. With ArangoDB they have a solid high performance technology for multiple purposes to simplify their tech stack. We are pleased that our vision got recognized by such a prestigious award. Now it’s about exceeding the rising expectations.”
Red Herring’s jury evaluated companies on both quantitative and qualitative criteria, such as financial performance, technological innovation and intellectual property, DNA of the founders, business model, customer footprint and addressable market. A review of the track record and standing of startups relative to their sector peers, allowing Red Herring to see past the “buzz” and making the list a valuable instrument of discovery and advocacy for the most promising new business models in Europe, complement this assessment of potential.
ArangoDB was chosen for its innovative and highly flexible multi model approach and for its massive growth on the business and community side over the past year. “In 2017, selecting the top achievers was by no means a small feat,” said Alex Vieux, publisher and CEO of Red Herring. “In fact, we had the toughest time in years because so many entrepreneurs had crossed significant milestones so early in the European tech ecosystem. We believe ArangoDB embodies the vision, drive and innovation that define a successful entrepreneurial venture. ArangoDB should be proud of its accomplishment, as the competition was very strong.”

Introducing milestone release model and why is it better
